Sometimes systems which reward luck are better than systems which purely reward money. If scalping exists, it often completely eliminates people who are too poor, even if they are true fans or interested parties (e.g. locals unable to attend sports games held in their cities, etc)

Scalpers raise the price only to transfer who loses out — as per your example, where they receive a fee to manipulate which customer misses out (and do so contrary to the wishes of the original vendor).

If you entire business is helping the rich ensure the poor lose and raise the price in general, despite what the original provider may have wanted, you are undoubtedly a bad person.
